Errors when using package
No Rosinstall 0.5 Libraries
ERROR Cannot find rosinstall libraries, check your installation. One frequent cause is that rosinstall 0.5 is still installed in /usr/local/lib. Check the rosinstall wiki for solutions. No module named pkg_resources
Be sure to read the line following the complaint. The above hints that it is missing the python module 'pkg_resources' which is in setuptools. Usually it will be this, or another dependency that is missing.
